Automatic winnowing filtering device

Abstract

The invention discloses an automatic winnowing filtering device. The automatic winnowing filtering device comprises a material collecting device, a conical air return opening, an air channel, a centrifugal machine, an air outlet and a dust collecting bin. The automatic winnowing filtering device is characterized in that the material collecting device is connected with the conical air return opening; the conical air return opening is connected with one end of the air channel into a whole; the other end of the air channel is communicated with the centrifugal machine; the air outlet is formed in the centrifugal machine; the air outlet is connected with the dust collecting bin. The automatic winnowing filtering device used during package of titanium sponge is simple in structure, small in occupied space and capable of sorting out impurities with small grain size, small weight and high adsorptivity in the package process, reducing the carbon content in products and improving the product quality.

Description

technical field [0001] The invention relates to an automatic winnowing and filtering device, in particular to an automatic winnowing and filtering device in the packaging process of sponge titanium. Background technique [0002] Titanium sponge is an indispensable basic link and intermediate product for making titanium ingots and even titanium materials. The cost of refining sponge titanium and melting and casting titanium ingots is relatively high, which restricts the development of the titanium industry and affects the wide application of titanium. my country's titanium sponge production areas are mainly concentrated in Guizhou, Liaoning, Henan, Hebei, Sichuan and Shanxi. The national standard stipulates that titanium sponge is divided into 6 grades according to hardness. Titanium sponge is loose and porous, with a large surface area, relatively active, and easily oxidized. Titanium sponge is not easy to store for a long time. my country's titanium sponge production area...

Problems solved by technology

[0005] The titanium sponge production standard GB / T2524-2010 requires that the impurities mixed into the product at various stages should be selected during the crushing and packaging process of titanium sponge production to maintain the purity of the product , the production process generally adopts the method of selection and magnetic separation to select chloride, iron and defective products in the product, but the carbon impurities mixed into the product by the conveyor belt during the crushing process are difficult to select due to small particles, light weight and strong adsorption , often resulting in excessive carbon content in products
